The main particularity of this pong system is that it is very very very small! The pads are only 2 x 6 cm. It looks like it had been made for dwarves or very little kid hands. Though this must have been a kind of marketing feature (so small you can take it with you anywhere you want), it also must have reduced the manufacturing costs...
The speaker hole takes a third of the front panel! The tiny controllers are mounted on each side of the system, but can also be detached to play in the sofa ;-)
The finition is very sober, but doesn't seem to be very strong. There are no screws to fix the different parts. It was very cheap.
The same system was also sold as the Riva T-800c and under the Tammy brand (in Finland).
